Engineering changes

An engineering change identifies the product and the transition from an existing revision to the intended revision. Product Engineer prepares the change number, effective date and source evidence. Engineering Reviewer examines that submitted basis and decides whether the request can move from Review to Approved. Approval gives the team a reviewed proposal to implement; the implementation action records the next operating result.

The change action checks product identity and attributed scope before proceeding. Invalid, duplicate and already-completed requests receive a reasoned refusal. Eligible work follows Draft, Review, Approved and Implemented. Keep the change number visible throughout that path so the reviewer and production team discuss the same request when they investigate a delay or correction.

• Describe the transition. Name the product and enter the old and new revisions with the intended effective date. Give the reviewer enough source evidence to explain the requested change.
• Make the decision attributable. Engineering Reviewer examines the submitted evidence and approves the change basis. Ask Product Engineer to resolve questions about the submitted source before making the decision.
• Confirm implementation. Product Engineer applies approved scope and inspects the resulting state. Production Planner then reviews the refreshed work-order detail and engineering-change screen for operating follow-up.

Agree revision naming, the meaning of the effective date and the evidence the reviewer requires. Rehearse an ordinary approval with the deciding person. Agree how the team handles a declined request and prepares corrected scope before another review. Confirm that each participant can perform the action assigned to their responsibility.

Agree how the reviewed design basis reaches the production team and how affected work is identified. Ask Production Planner to explain the instructions needed before release. Set a practical review routine for approved changes awaiting implementation, including who follows up when the intended effective date approaches. Design repository connections and detailed production instructions are setup choices to agree with their owners.

Prepare a housing change from revision A to B with the intended product and effective date. Submit the Draft request with attributed source evidence and inspect its move to Review. Engineering Reviewer checks the design basis and records the approval. Product Engineer then applies the approved scope and checks that the change is marked Implemented.

Replay the completed request. The refusal should identify the completed scope without applying it again. Try a duplicate submission and inspect its reason. Finally, open the refreshed work-order detail and ask Production Planner which work needs attention. The planner and reviewer should explain the same design basis before the team releases affected work. Resolve a disagreement through the supported change process and retain the source evidence.

• Engineering change board — Follow change requests by current state and revision transition.
• Engineering review inbox — Inspect the requests awaiting Engineering Reviewer decisions.
• Approved changes to implement — Find reviewed scope that still needs its implementation action.

Review and implement changes covers the decision. Release production follows the operating checks. Review the data model during setup.
